set up a test enviroment to test VPN connections that will be used in production systems. I have Server A and Server B Server

Vpn Error 691 The Remote Connection Was Denied

A : Domain Controller,DNS, RRAS (Windows Server 2008) Server B: RRAS (Windows Server 2008 R2) I have set up PPTP and L2TP(PSK) on Server A and it works fine (MS-CHAPv2). I can connect i can change authentication etc.. On Server B however i am facing a problem. I fail the connection was prevented because of a policy configured on your ras/vpn server to connect to server B no matter what settings i try. I always get the error code 691. I have checked all the settings, the RAS group in AD, the credentials (it's the same test account..) but still nothing. I used wireshark to analyze the packets and everything works fine until the CHAP authentication where the Server B responds with PPTP Chap authentication failure. The packets that are sent to Server B are identical to the ones that are sent to Server A. The same authentication options, PPP LCP options etc Needless to say connection security policies on RRAS are empty, NPS-NPS/RADIUS-NPS/NAP are not installed. No particular Group Policy applied. I tried changing the Accounting setting on security tab to be None/Radius (pointed to Server A who is a DC), Windows authentication and still nothing. All i can see from the trace logs are authentication

Solved VPN Error 691 Posted on 2013-11-15 Windows Networking VPN Windows Server 2008 1 Verified Solution 16 Comments 1,623 Views Last Modified: 2014-07-25 event id I have found many articles referring to VPN Error 691 but no definitive answer. It is suggested by the error that username and/or password is invalid on the domain. Here is some more information - I recently took over from the IT Manager who copied his account to create mine, so I effectively have all the same permissions. There is one specific to our VPN event id 20271 and I have made sure I am within this group. I know the VPN is set up correctly because somebody took my laptop back to their house and tried their credentials and got on fine, they then tried mine and got the VPN 691 error. Obviously I know my credentials to be fine (they work internally) but I have noticed the following security event on the server when it fails - Log Name: Security Source: Microsoft-Windows-Security-Auditing Date: 15/11/2013 12:25:37 Event ID: 4625 Task Category: Logon Level: Information Keywords: Audit Failure User: N/A Computer: UKHARINF01.goptions.local Description: An account failed to log on.

I validated that the username and password are correct. I also installed a certification to use with the IKEv2 security type. I also validated that the VPN server support security method. But I cannot login. In the server log I get this log: Network Policy Server denied access to a user. The user DomainName\UserName connected from IP address but failed an authentication attempt due to the following reason: The remote connection was denied because the user name and password combination you provided is not recognized, or the selected authentication protocol is not permitted on the remote access server.
